Product Details
✓Mechanical Filtration: The mini aquarium sponge filter can effectively trap debris, food residues, wastes or other impurities in water. Prevent them from entering the aquarium to keep water clean.
✓Deep Cleaning: Contain mini filter balls on the bottom. They are helpful for blocking large particles in the water and accumulating beneficial elements. Provide biological filtration to fully remove excess harmful substances.
✓For 5-20 Gallon Tanks: Size: 3.2" W x 2.2" H. Fit for 5 to 20 gallon fish tanks. Suitable for the breeding and feeding of various ornamental fish, shrimp or fish fry.
✓Quiet Aeration: Air powered aquarium filter – required air pump: < 4 W; jetting volume of air stone: 0.8 L/min. The bio sponge filter produce a cascade of dense bubbles in the water, greatly promoting oxygen circulation to keep your fish healthy.
